Frigidaire FED365EQD Range - Six months ago after baking, cooling fan stayed on all night. Someone (I found online) told me to experiment with Clear/Off (controls) button. Eventually it did shut off. Next time fan stayed on, no luck with the buttons. Killed the breaker and fan was off next morning. Have killed the breaker 6-8 times since to shut fan off (always after bake use). No problems with rest of the range, only the oven fan. From schematic I'm guessing stuck cooling fan relay, or the Fan Holding thermostat that's in parallel with relay contacts. Does this sound right? It's a hard-wired built-in.

Assuming I'm on the right track, where are the relay and thermostat physically located?

Looking at The Diagram for your range I would say it's on the back of the range. Part 119 on the diagram list it as a switch and when you look at it in the part list (F119) the so called switch looks like a thermostat.

Great. I appreciate your help. Glad you also think their switch is a thermostat. The "switch" made no sense to me. You gave me the courage to pull the beast out and test the part, then look at relay contacts while I'm at it. My first (and a GOOD) experience at this site! Regards.
